Is it time to upgrade?

• Electrical service & distributionFinaled permit foundLast permitted 2004 (22 years ago). Worth reading the permit itself: it names the service but does not read as an increase in capacity, so this may have been a like-for-like replacement rather than an upgrade. Separately from replacement: NFPA 70E expects the arc-flash study to be reviewed at least every five years, or after any change to the service.

• Heating, cooling & mechanicalFinaled permit foundLast permitted 2016 (10 years ago). Packaged rooftop units work harder in Tucson than almost anywhere, so 12 to 15 years is a realistic service life rather than the 15 to 20 the industry quotes. T16CM02449 — ADD HVAC AND ELEC LOAD CAPACITY IN TELEPHONE ROOM
• Fire alarm & life safetyFinaled permit foundLast permitted 2024 (2 years ago). Panels and devices age out on their own schedule, and the code moves underneath them — a system that was compliant when installed is not automatically compliant now. TF-FCP-1124-01003 — Fire sprinkler system
• RoofNot in this windowNothing in the permit records we read for this parcel that names this system. Roof age matters electrically too: it sets what can be penetrated for new rooftop units, conduit, or solar.

A found permit means a lot. A missing one means less. We read the City of Tucson’s own permit file, not a recent extract of it — back to about 2006, and into the 1990s on properties with that much history. Microfiche before then was never fully digitized. Every record links to the city’s official file. A blank line does not say nothing was done: work gets done without permits all the time. The only way to know what is actually installed is to look at it.

What that usually means electrically

• Era-based check

  A finaled 2004 panel/service permit is on record for this parcel, which makes it unlikely the original 200 A equipment is still in place. That is a permit record, not an inspection — verify the installed rating and the panel brand on site before sizing anything new. The permit record does not confirm this; an on-site inspection is required.

• Era-based check

  NFPA 70E expects arc-flash studies to be reviewed at least every five years, or after any change to the service. Buildings this age often have labeling that no longer matches the installed gear. The permit record does not confirm this; an on-site inspection is required.

• Worth confirming

  Industrial and warehouse space usually means three-phase motor loads. High-bay LED retrofits and added VFDs both change the load picture.

• Routine

  A trade permit was pulled in 2016. Trade permits cover electrical, plumbing, and mechanical work individually, so some permitted trade work has been done here since.

Solar and energy potential

Roof footprint

≈ 83,355 sq ft (county building-footprint layer, 2 structures)

Usable for solar, planning estimate

≈ 58,300 sq ft (~70% after setbacks, rooftop equipment and access paths)

Array that could fit

on the order of 640 kW — roughly 1,600 panels (low-tilt ballasted rows, 400 W class modules)

Estimated annual production

≈ 1,050,000 kWh (PVWatts, Tucson sun, low-tilt south)

Energy-charge offset at TEP commercial rates

$84,000–$137,000 a year (8–13¢/kWh energy + power-supply charges, by season and rate class)

Planning-level arithmetic on the roof area above — not a shading study, a structural review or a design. The offset assumes the building uses the power as it is generated; TEP pays far less (its export rate is about 5¢/kWh) for surplus sent to the grid, so the load profile decides the real value. The 30% federal credit (§48E) still applies to commercial systems placed in service by the end of 2027 — projects that began construction by July 4, 2026 have longer; confirm timing with a tax adviser.

TEP grid capacity — mapped saturation areaThis property sits within about half a mile of “I-10 and Valencia Rd”, one of 11 areas TEP has mapped as saturated with distributed generation (customer solar) relative to circuit capacity. On a saturated circuit, new solar or battery systems can trigger supplemental utility review before interconnection is approved — and a large new load such as DC fast charging or process equipment is worth a capacity conversation with TEP before a site plan hardens. The boundary here is approximate, digitized from TEP’s map of the area (PDF, July 2020); TEP’s own interconnection screening is the authority, and circuit status can have changed since the maps were published.

The building area above comes from the Pima County Assessor’s record, as we read it on 28 Jan 2026. Each other row names its own source.

The most recent permitted work on this parcel was in 2025. That says the parcel was worked on under permit, not what the work covered — a roof, a pool or a changeout tells you nothing about the electrical service. Work done without a permit leaves no trace here at all.

This is an inference from public records — the year a structure was built, how it is classified, and what has been permitted. It is not an inspection, and nothing here confirms what is actually installed at this address. The only way to know is to look in the panel. See an error in this public-record report?

Utility and upgrade pathElectric service here is Tucson Electric Power (TEP). A service or panel upgrade needs a TEP meter release and has to meet TEP’s service requirements — meter height and location, clearances, and the point of attachment. See TEP new-service requirements and the TEP standards notes.

The contractor’s read is a plain-English brief of the record above, written by AI — what it shows across electrical, mechanical and the building itself, what is missing for the era, and what to verify on site.

What the flood note is not. The flood zone shown is FEMA’s National Flood Hazard Layer — the federal insurance map. Local floodplain mapping is not reproduced here; use the authority’s own map, linked above. Nothing here is a floodplain determination, an elevation certificate, or a substitute for one. A parcel can straddle a boundary, and a Letter of Map Amendment can remove a structure the map still covers. For a determination, ask the floodplain administrator for the jurisdiction named above; for a design that has to satisfy one, that is work we do.
